Adjustable camshaft
An adjustable camshaft having at least one shaft, and having at least one cam package which has at least two different cams and/or cam contours. According to the invention, the cams and/or the cam contours of the cam packages have different widths.
1. An adjustable camshaft comprising:
at least one shaft,
multiple cam packages, each cam package having at least two different cams and/or cam contours, and
at least one adjusting element constructed to slide axially along a longitudinal axis of the camshaft,
wherein the cams and/or cam contours of at least one of the cam packages have different widths,
wherein the at least one adjusting element is mechanically coupled via at least one contact element through a groove in the at least one shaft to a first one of the multiple cam packages having cams and/or cam contours with different widths and being constructed to slide axially along the longitudinal axis of the camshaft relative to the at least one shaft,
wherein the at least one shaft is constructed to slide axially along the longitudinal axis of the camshaft,
wherein a second one of the multiple cam packaged is rigidly fixed to said shaft, and
wherein the at least one adjusting element and the at least one shaft are constructed to allow the first one of the multiple cam packages coupled to said adjusting element and the second one of the cam packages fixed to said shaft to be moved independently of each other.
2. A camshaft according to claim 1 , wherein:
at least two cam packages are mechanically coupled to the adjusting element.
3. A camshaft according to claim 1 , wherein the adjusting element is constructed to rotate radially about the longitudinal axis of the camshaft.
4. A camshaft according to claim 1 , wherein at least one axial adjusting device is included which is connected to the adjusting element, and which displaces the adjusting element axially, at least segmentally.
5. A camshaft according to claim 1 , wherein multiple adjusting elements are included which are constructed to slide axially along the longitudinal axis of the camshaft.
6. A camshaft according to claim 1 , wherein the adjusting element is constructed as a solid cylinder, or as a tube, or as a segment of a cylinder, or as a segment of a tube, or as a sheet metal part.
